VETERINARY OBSTETRICAL INSTRUMENT.

Specification of Letters Patent.

Patented June '7, 1910.

Application filed December 13, 1907, Serial No. 406,335. Renewed May 9,1910. Serial No. 560,315.

To all whom it may concern:

Be it known that I, CHARLES GABEL, a citizen of the United States,residing at Hawkeye, in the county of Fayette and State of Iowa, haveinvented certain new and useful Improvements in Veterinary ObstetricalInstruments of which the following is a specification.

This invention relates to obstetrical instruments, and more particularlyto a forceps adapted for use in the delivery of pigs, however, it may beused with excellent results and great efficiency in the delivery ofother animals, thus, I do not confine the use of my instruments toperforming obstetrical operations on hogs only.

The object of my invention is to construct an obstetrical instrumentwhich is thoroughly antiseptic as it can be readily sterilized owing toits simplicity of construction.

A further object of my invention is to construct an obstetricalinstrument with but few parts, so constructed and arranged that allpossibility of the instrument getting out of order is avoided, also theproduction of an instrument which is durable, reliable and Willefficiently perform all of its intended functions.

With these ends in view, my invention consists in the construction ofthe parts, and in the combination and arrangement of said parts all ofwhich will be hereinafter more fully described and specifically pointedout in the appended claim.

I have found by experience that by providing the flexible gripping loopwith a central outwardly projecting coil or eye 11, which when the loopis flat or disconnected from the brace rod 14, lies in substantially thesame plane as the loop; and that the coil or eye not only provides aconnecting means for holding the brace rod 14 centrally of the loop, butassists in opening the loop. This I have found accomplishes this secondresult, on account of the peculiar formation of the coil or eye, whoseterminals are given a tension away from each other, thus acting to openthe loop.

In the drawings, a perspective view of my instrument is shown.

Referring by numerals to the drawings, 1 represents a short transversesection of heavy wire the respective ends of which are bent back underthe transverse section, so as to form corresponding eyes 2, and arebrought together at a point 3, from which point the said ends aretwisted together so as to form a shank 4:, with several eyes or loops 5,6, 7 and 8, arranged throughout its length. One of the eyes 5, isarranged at or near the point 3, beneath the shank and the remainderupon the top of the shank the object of which will hereinafter appear.The ends of the wires forming the shank, terminate in a handle 9, bywhich the instrument is manipulated.

A wire loop 10, which is rovided with an eye 11, has its respective en spassed through the eyes 2, thence through the eye 5, crossing each otherat a point 12, thence up through the eye 6, and along the shank throughthe remaining eyes 7 and 8 and twisted together so as to form a handle13, by which the said loop may be contracted or expanded. Engaging theeye 11, upon the loop, is a rod 14:, which connects said loop to the eye6, upon the shank, the object being to curve the loop backward whenexpanded and to lend rigidity thereto.

The loop 10 is provided with the central coil or spring 11 which gives aspring tension to the terminals of the loop so that after the instrumentis inserted, the loop having been previously contracted, this spring 11,will assist in the expanding, spreading or opening of the loop. It aswell serves as a fastening means for the rod 14.

It is to be understood that I do not limit myself to the exact detailsherein shown and described as I may without departing from the spirit ofthe invention make various changes therein. I may place or form theguides thereupon in any suitable and convenient manner and at anydesired location all of which is within the scope of my invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

In an obstetrical instrument, a twisted Wire shank having a handleformed upon one end and outwardly and upwardly diverging guides upon theother, a series of guides upon the shank, a Wire 100p having itsdiverging ends passed through the respective guides upon the end of theshank, brought together, crossed and passed through the guides upon theshank and terminating in an integral handle, and a rod connecting theloop to the shank,
